WIND-OPERATED WATER-ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 789,042, dated May 2,1905.

Application filed April 15, 1904. Serial N0v 203,315.

To all whmn it may concern.-

Be it known that 1, LEE W. MAxoN, a citizen of the United States,residing at Johnson, in the county of N emaha and State of Nebraska,have invented new and useful Improvements'in Wind-OperatedWater-Elevators, of which the following is a specification.

My invention relates to wind-operated water-elevators, and is in thenature of an improvement on a previous device of the same kind patentedto me and bearing No. 232,531 and dated September 21, 1880.

The invention relates more specifically to a new means for controllingthe blades of the wind-wheel, whereby they may be so moved in relationto the wind as to become inoperative without the controlling influenceof a vane, and to mechanism for producing this result.

It also relates to a retarding device for preventing a too rapid descentof the bucket, and to means for controlling the discharge of the bucketwhen raised by the wind-wheel, and also, generally, in the details ofconstruction and the combination of parts described in the specificationand illustrated in the accompanying drawings.

In the drawings, Figure l is a front elevation of the wind-wheel andhoisting mechanism; Fig. 2, a side elevation of the same; Fig. 3, asectional view on line 3 3 of Fig. 1 with the parts in position toelevate the bucket; Fig. 4, a similar view With the parts in position tolower the bucket; Fig. 5, a detail view of the bucket and dischargingmechanism with the bucket ascending, and Fig. 6 a similar view with thebucket in discharging position. Fig. 7 represents an enlarged detailfragmentary view of the vane-actuating links and surrounding parts.

Referring to the drawings, A is a windwheel mounted upon a horizontalshaft B, carried in a bearing C in the end of a bracket D, which ispivotally mountedin a castingE, forming a turn-table and provided with acentral opening E, through which an elevatorrope may be passed, as willbe further described, carried at the upper end of a tower F of any usualor preferred construction which will permit the free movement of thewheel around the tower.

The wind-wheel A is composed of a series of blades 1, pivotally mountedat their front edges by pins 2 and 3 to annular rings 4 and 5, carriedby radial arms 6 6 6 6, secured to a casting 7, forming the hub of thewheel and carried by the shaft B. An annular ring 8 is pivotally engagedby crank pins or links 9, carried by the edges of the blades 1, at apoint intermediately between the rings 4: and 5, whereby the blades bythe rotation of rings 8 may be rotated upon their pivots and thrown intoor out of operative relation to the wind. The ring 8 has a limitedmovement of rotation about the shaft B and is controlled in its movementin one direction by rock-shafts G G, mounted in suitable bearings 11 11upon the arms 6 6, and its opposite movement by spiral tension-springs12 12, connected at one end to the annular ring 8 and at their other endto the arms 6 6. The rock-shafts G G are formed with angular extensionsor crank Qmembers 13 13 at their outer ends and pro-.

vided with short sections 14 14 parallel to the shaft, which entersuitable openings in the annular ring 8 in such manner that the rotationof the shafts G G will impart a rotary movement to the ring 8 around theshaft B, between the hub of the wheel A and the bearing O. The collarHis provided with lugs 15 15, to which are attached links 16 16, whichslide through bearing-lugs 17 17, mounted on the hub of the wind-wheeland provided with rearwardly extending arms 18 18, which are connectedto angular extensions or cranks 19 19, formed on the inner ends of therockshafts G G at right angles to the extensions or cranks at theirouter ends. From this construction it follows that theforward-and-backward movement of the collar H on the shaft B will imparta rotary movement to the shafts Gr G and through the annular ring 8rotate the blades of the wind-Wheel and throw them in or out ofoperation.

The movement of the collar H is controlled by a forked bell-crank leverJ, pivoted to the bracket D. The upright forked end 20 of this leverengages annular groove 21 in the collar H, and the rearward horizontalextension 22 of the lever rests upon an annular horizontal flange 23,carried by a ring 24, which surrounds and is adapted to slide in avertical direction upon the casting E, its movements being under controlfrom the base of the tower by a vertical rod K, moved by a hand-lever orany other suitable means, said rod K engaging at its upper end abell-crank or elbow lever 7c, in turn engaging flange 23. The elbow orbell-crank lever is (seen in Fig. 2) has its upper-end engaging theflange 23 in such manner as to effect a slight upward movement of theflange 23 when the rod K is pulled downwardly, this movement being dueto the swinging of the upper end of the bellcrank lever K through thearc of a circle as the lever moves upon its pivot, so that regardless ofthe position of the lever J its arm 22 may be actuated through operationof the rod K, the free end of the arm 22 of course resting at all timesupon the flange 23, regardless of the extent of rotation of the bracketD and parts carried thereby.

In the rear of the bearing in the bracket D is mounted the mechanism foroperating the water-elevating device, which consists generally in a drumL, loosely mounted upon the wind-wheel shaft; a tripping-clutch M forconnecting and disconnecting the drum from the shaft; a tripping-leverN, controlled by the movement of the elevator-rope for operating theclutch M, and a detent-fan O, operated by the rotation of the drum forpreventing the too rapid descent of the bucket. The drum L consists of acylinder loosely mounted on the shaft and provided with flanges 25, therear flange being provided with gear-teeth 26, adapted to mesh with apinion 27, carried on a short shaft 28, mounted in a bearing 29, carriedupon the upper side of the turn-table casting E. The outer end of theshaft 28 carries the detent-fan O, which may be of any construction, butis preferably in the form of a series of curved blades 30, adapted tooffer resistance to the air and supported and reinforced at their outerextremities by an annular ring 31. Between the drum L and the bracket Dis mounted the clutch mechanism, which consists of an angular dog 32,mounted in a collar 33, secured to the wind-wheel shaft with one armsubstantially parallel to the shaft and the other adapted to engage alug 34, carried by the drum L. The dog is normally held out ofengagement with the lug by a spring 35, but can be thrown in position toengage the lug by means of a shifting cone 36, adapted to slide on thewind-wheel shaft. This cone is provided with an annular groove 37,adapted to engage the end of a bell-crank lever 38, pivoted to the"inner sideof the bracket D and provided with a horizontal member 39,carrying at its outer end a pivoted link 40, provided with an openingthrough which the elevator-rope 41 passesin such manis an uprightweighted lever P, provided with.

a short arm 43, which engages the annular groove 37 'in the cone 36, theoffice of which is to hold the parts in their shifted position andprevent accidental displacement of the same when in either position.

The lower end of the rope 41 is attached to a bucket Q, provided at itsbottom with a hinged valve opening upward and adapted when raised toenter a casing R, provided with a hinged discharge-spout S.

The casing R is provided with guides 44 44, adapted to slide on verticalguide-rods 45, movement being imparted to said casing by a flange 46 atthe lower end of the bucket Q, which engages the lower edge of thecasing R and lifts it along its guides. The discharge-spout is hingedtothe lower edge of the casing and provided with an elbow 47, whichcarries an arm 48, provided with a wheel 49, adapted to make contactwith a cam-track 49, having an inclined surface 50, which causes thedischarge-spout to rotate upon its hinge upon the upward movement of thecasing and make contact with the lower end of the bucket. The upper endof the discharge-pipe carries a pin 51, adapted as the spout is turnedon its hinge to make contact with and lift the valve in the bottom ofthe bucket and permit the discharge of its contents.

It is to be understood that the stops on the rope may be moved to allowfor different depths of water and heights of tower.

What I claim, and desire to secure by Letters Patent, is-

1. In a device of the class described, the combination with a hub andradial arms extending therefrom, of rings fixedly carried by said arms,blades pivotally carried by said rings, a ring linked to said blades,rock-shafts engaging said last-mentioned ring for moving the same in onedirection, means for moving the same in an opposite direction,bearinglugs carried by said hub, links longitudinally movably mounted insaid bearing-lugs, extensions carried by said links engaging saidrockshaft for rocking the same, and means for actuating said links.

2.
